Step 1: Understanding Hume’s Principle of Causality.
David Hume's principle of causality posits that causation stems from observing regular succession and contiguity between events. Hume contended that necessary connection is not directly observable; instead, causality is inferred from the consistent conjunction of events.
Step 2: Analyzing the Options.
- 1. The two events are in conjunction with each other: This is accurate. Hume asserted that for one event to cause another, they must occur together (conjunction). - 2. The two events are in proximity to each other: This is accurate. Proximity, or temporal nearness, is crucial in Hume’s perspective on causality. - 3. The two events have a necessary internal connection: This is inaccurate. Hume rejected the existence of an observable "necessary connection," arguing that causality is inferred, not perceived.- 4. The two events are contiguous: This is accurate. Contiguity, referring to the closeness of events, was considered important by Hume for causality.
Step 3: Conclusion. The correct option is 3. The two events have a necessary internal connection.
Final Answer: \[ \boxed{\text{The correct answer is 3. The two events have necessary internal connection.}} \]
